When using the preview by layer or line, the only options to move through the layers / lines is to use the horizontal scroll bar or the arrows at the far right of the screen. Can you add the ability to use the left/right arrow keys on the keyboard to move through the layers or lines? Either using the arrow key to move one layer / line at a time with each arrow button push, or when holding the arrow key down, rapidly move up or down in layers / lines. I feel this would be a productivity improvement to the current version.
